celebrities pairs you didn’t realize were best friends

Sienna Miller and Keira Knightley

Miller and Knightley have long been spotted on the red carpets together. The British superstars met in 2008 when they worked on “The Edge of Love” together. Knightley was struggling with a break-up when Miller suggested that they get drunk and make total fools out of themselves to get through it. Her advice worked and they’ve been close-knit ever since.
